Last updated on JULY 12, 2019

Applies to:

Oracle VM - Version: 2.1.5

Symptoms

You are trying to perform a live migration on Oracle VM Manager. However, the status of the VM keeps in 'Migrating' after migration.

Checking the VM status on virtual machine servers (dom0), you get the following status:

on source
#xm list
Name          ID Mem VCPUs State  Time(s)
migrating-vm  14 1024  1   -b---- 9020.5

on target:
#xm list
Name ID  Mem VCPUs State  Time(s)
  vm 22 1024  0    -bp--- 0.0
 
Though the migration is hanging, the VM can still be connected via ssh.

Changes

It's an Oracle VM 2.1.5 installation. The guest in question is a HVM with RHEL/EL4U7 installed:
#uname -a
inux vm 2.6.9-78.EL #1 Wed Jul 9 15:27:01 EDT 2008 i686
